Fire and Explosion Risks:

  • Fires and Explosions generate a high risk for people, the environment and production installations. The consequences are the significant development of heat and pressure.
  • The fire and explosion safety of an installation is determined by risk factors of the process and products.
  • High drying temperatures and material product characteristics can develop dangerous smouldering ἀres in the production process.
  • Use of Carbon Monoxide (CO) Analysis for early fire detection is recommended according to VDI guideline 2263 part 7 and 7.1 and the robecco CO System is a proven technology.
  • Early detection of smouldering fires allows the operators to mitigate fire propagation with help of technical measures. Continuous Carbon Monoxide (CO) monitoring is essential to ensure prevention against fires and explosions.

Robecco Dryer Protection (RDP)

The robecco dryer protection (CO System) avoids production stops and ensures productivity. It provides a continuous monitoring of the dryer system to detect smouldering nests or fires in a spray drier. Carbon monoxide is a gas that is given off during the Maillard reaction for example in Milk Powder spray driers when smouldering occurs due to product buildups at elevated temperatures. The Robecco CO system will detect at an early stage the development of this hazard and activate alarms and enable the user to implement emergency shutdowns or a combination with the plant’s water deluge system

Robecco Dust Control (RDC)

The Robecco dust control (broken bag detector) determines in an effective way damages in filter separators. Optimisation of emission and filter monitoring guarantees high productivity. The RDC can be added as part of the robecco CO System.

Technical Characteristics:
· Emission and filter monitoring with one device
· Avoidance of visible exhaust gas plumes
· Avoidance of product losses
· Simple erection and installation

Simple maintenance of filter installations because of:
· Early detection of ongoing bag filter damage
· Location of damaged filter elements
· Opportunity for specific maintenance actions

Applications (examples): Emmission and filter monotoring in
· Process filter
· Silo roof filter
· Dedusting systems
